The nurse is caring for the client experiencing Guillain-Barre syndrome (GBS). It is most important for the nurse to monitor the client for which complication?

A) Monitor the client's pulse oximetry every shift:
Monitoring pulse oximetry every shift is not sufficient when caring for a client on a ventilator. Pulse oximetry provides valuable information about oxygen saturation, but it should be checked more frequently, especially in a critically ill patient on a ventilator. Continuous monitoring may be required to ensure that oxygenation is maintained at optimal levels. The nurse should assess the pulse oximetry regularly and take immediate action if there is a significant change in the client’s oxygen saturation.

B) Assess the client's respiratory status at least every 1-2 hours:
It is essential to assess the client's respiratory status frequently when they are on a ventilator. Respiratory assessments should be performed at least every 1-2 hours to monitor for complications such as ventilator-associated pneumonia, changes in oxygenation, or the need for adjustments to the ventilator settings. Regular assessment is critical to detect early signs of deterioration and respond promptly.

C) Ensure that a manual resuscitation bag is at the bedside:
Having a manual resuscitation bag (e.g., Ambu bag) at the bedside is a critical intervention for clients on a ventilator. In case of ventilator malfunction, extubation, or respiratory distress, the nurse must have immediate access to a resuscitation bag to manually ventilate the patient. This is a lifesaving piece of equipment that should always be present and ready for use.

D) Check the ventilator settings every shift:
It is essential to check ventilator settings every shift to ensure that the ventilator is functioning correctly and providing the appropriate levels of support for the patient. This includes checking settings such as tidal volume, respiratory rate, pressure, and FiO2 (fraction of inspired oxygen) to ensure they are appropriate for the client's condition. Regular checks can help detect problems such as changes in settings or malfunctioning equipment.

E) Collaborate frequently with the respiratory therapist:
Frequent collaboration with the respiratory therapist is crucial when managing a client on a ventilator. Respiratory therapists are experts in ventilator management and can provide valuable insight into adjusting settings, interpreting ABGs, troubleshooting equipment issues, and optimizing respiratory care. Collaborative care helps ensure that the client is receiving the most appropriate interventions and adjustments for their respiratory status.

A) Endotracheal intubation with mechanical ventilation:
Given the client’s lethargy, slow response to commands, and critical vital signs (e.g., low blood pressure of 88/52, high pulse rate of 132, respiratory rate of 8, and oxygen saturation of 84%), the client is in severe respiratory distress and may be at risk for respiratory failure. The low SpO2 of 84% on a 35% Venturi mask indicates that the client is not adequately oxygenating despite non-invasive oxygen support. In such situations, endotracheal intubation with mechanical ventilation is required to ensure adequate ventilation, oxygenation, and airway protection. This is the most appropriate intervention for a client in respiratory failure who is not responding to less invasive interventions like oxygen therapy or non-invasive ventilation.

B) Use of bi-level positive airway pressure ventilation (BiPAP):
BiPAP is a non-invasive ventilation option that is often used for patients with respiratory failure, particularly those with obstructive or central sleep apnea or those in the early stages of acute respiratory failure (e.g., chronic obstructive pulmonary disease exacerbations). However, given the client’s level of lethargy and deteriorating vital signs, BiPAP may not be sufficient. This client is showing signs of severe respiratory distress and requires more invasive management, such as endotracheal intubation and mechanical ventilation, to maintain an open airway and ensure adequate oxygenation and ventilation.

C) Administration of 100% oxygen by mask:
While oxygen administration is essential to manage respiratory failure, providing 100% oxygen via mask alone is unlikely to resolve the client's underlying issues, especially since the client’s oxygen saturation is critically low (84%) on 35% Venturi mask. Simply increasing the oxygen concentration will not be effective if the client’s respiratory failure is severe and the airway is compromised. More aggressive interventions, such as intubation, are necessary to manage the client’s airway and respiratory function appropriately.

D) Insertion of an oral airway device to maintain the airway:
An oral airway device is typically used for clients who are unconscious or semi-conscious to help keep the airway open. However, in this case, the client is lethargic but not fully unconscious, and the underlying issue is respiratory failure, not just a blocked airway. An oral airway device will not address the client’s inadequate ventilation or oxygenation and will not be sufficient to manage the client’s critical condition. The client requires intubation and mechanical ventilation to ensure adequate airway management and respiratory support.
